There has been a continual debate on which programming language/s to learn, to use. As the latest TIOBE Programming Community Index for August 2021 indicates – C (13%), Python (12%), C++ (7%), Java (10%), and C#(5%) together control nearly half the programming activities worldwide. Further, C Programming Language Family (C, C++, C#, Objective C etc.) dominate more than 25% of activities. Hence, learning C++ is important as one learns about the entire family, about Object-Oriented Programming and gets a solid foundation to also migrate to Java and Python as needed. C++ is the mother of most general purpose of languages. It is multi-paradigm encompassing procedural, object-oriented, generic, and even functional programming. C++ has primarily been the systems language till C++03 which punches efficiency of the code with the efficacy of OOP. Then, why should I learn it if my primary focus is on applications? This is where the recent updates of C++, namely, C++11 and several later offer excellent depths and flexibility for C++ that no language can match. These extensions attempt to alleviate some of the long-standing shortcomings for C++ including porous resource management, error-prone pointer handling, expression semantics, and better readability. The present course builds up on the knowledge of C programming and basic data structure (array, list, stack, queue etc.) to create a strong familiarity with C++98 / C++03. Besides the constructs, syntax and semantics of C++ (over C), we also focus on various idioms of C++ and attempt to go to depth with every C++ feature justifying and illustrating them with several examples and assignment problems. On the way, we illustrate various OOP concepts. The course also covers important advances in C++11 and later released features..

using namespace std;
class B{
    protected:
        int b1;
    public:
        B(int b) : b1(b){}
};
class D{
    protected:
        int b2;
    public:
        D(int b) : b2(b){}
};

class DD : public B, public D{ //LINE-1

    int d;
    public:
        DD(int x) : B(2*x), D(3*x), d(x){} //LINE-2

        void show(){
            cout << d << ", " << b1 << ", " << b2;
        }
};

    public:
        friend void studDetails(const Student&); //LINE-1
};
class Bengali : public Student{
    public:
        Bengali(string n, int m) : Student(n, "Bengali", m){} //LINE-2
};
class English : public Student{
    public:
        English(string n, int m) : Student(n, "English", m){} //LINE-3
};

void studDetails(const Student &st){
    cout << st.n << " --> (" << st.s << " - " << st.m << ")";
}

int main(){
    string s;
    int m, n;
    Student *st;
    cin >> m >> s >> n;
    if (m==1)
        st = new Bengali(s, n);
    else if (m==2)
        st = new English(s, n);
    studDetails(*st);
    return 0;
}
